Johathon,

In the interest of NST protection during these trigger gap experiments,
you may wish to run the coil at a rather low power, by using an input
main variac on the coil, and setting it low, at half or 3/4 level or so.
This way you can restore the original safety gap setting while you're
testing things.
If you''re using an LTR cap, that will also go a long way towards 
protecting the NST by preventing resonant build up, during times
when the trigger gap fails to fire.  If you're using a resonant or matched
size cap, the NST will probably be destroyed during experimentation.
